The word 'backlight' combines 'back', meaning 'behind', and 'light', which refers to illumination. The usage of the term can be traced back to the rise of digital displays in the late 20th century when manufacturers began developing technologies to improve the brightness and contrast of screens. As LCD technology advanced in the 1990s and 2000s, the term 'backlighting' became widely used to describe the method of illuminating the screen from behind for better image quality. This advancement became critical for consumer electronics, such as televisions, computer monitors, and mobile devices, marking a significant evolution in display technology.
